Abstract
An electrical energy transmission device has phase conductors, which carry alternating current and have transfer impedance, and sheathed conductors, which are inductively coupled to the phase conductors. A first end and a second end of each sheathed conductor form a sheath circuit with a reactance. An electronic assembly for changing the impedance of the sheath circuit is provided. The electrical energy transmission device can be used flexibly given different demands placed on the energy transmission. The electronic assembly is also configured to increase the transfer impedance.
Claims19
An electrical power transmission device, comprising:
- phase conductors for carrying alternating current and each have a transmission impedance;
- a reactance;
- casing conductors inductively coupled to said phase conductors and each having a first end and a second end, each of said first and second ends together with said reactance forming a casing circuit having a given impedance;
- and
- an electronic assembly for varying the given impedance of said casing circuit, said electronic assembly configured for increasing the transmission impedance.
